The DKR–Texas Memorial Stadium attendance record of 101,851 spectators was set on October 6, 2012, when Texas played West Virginia.

The stadium has been expanded several times since its original opening. The University's most recent completed project was a $27 million expansion and renovation project to the south end zone facilities in August 2009. For the 2009 season, 4,525 permanent bleacher seats were constructed, which allowed the stadium to become the first football stadium in Texas capable of seating in excess of 100,000 people[5] and brought the stadium to its current seating capacity. In May 2013, Regents for the University of Texas system approved a $62 million stadium improvement project. This project will improve and add athletic and academic facilities within the existing stadium structure, but it will not expand the current seating capacity.[6] The timeline for this project's completion has not yet been revealed.

In 1923, former UT athletics director L. Theo Bellmont (the west side of the stadium is named in his honor), along with thirty student leaders, presented the idea of building a concrete stadium to replace the wooden bleachers of Clark Field to the Board of Regents. Heralded as "the largest sports facility of its kind in the Southwest" upon its completion in 1924, the first unit of the stadium consisted of the east and west stands with a seating capacity of 27,000. It was designed as a dual-purpose facility with a 440-yard (400 m) track surrounding the football field. The stadium was financed through donations from both students and alumni. The estimated cost of the structure was $275,000.

The student body dedicated the stadium in honor of the 198,520 Texans — 5,280 of whom lost their lives — who fought in World War I. A statue, representing the figure of democracy, was later placed atop the north end zone seats of the stadium. In World War II, the University lost many former players, including former coach Jack Chevigny. The Athletics Council rededicated the newly enlarged stadium on September 18, 1948 prior to the Texas-LSU game, honoring the men and women who had died in the war. On November 12, 1977, a small granite monument was unveiled and placed at the base of the statue, during the TCU-Texas game. The ceremony rededicated Texas Memorial Stadium to the memory of all alumni in all American wars.

The University of Texas honored legendary football coach Darrell K Royal, who enlisted in the US Army Air Corps in 1943, and who led Texas to three national championships and eleven Southwest Conference titles, by officially naming the stadium after him in 1996. Additionally, the University established the Royal-Texas Memorial Stadium Veterans Committee, composed of alumni who served in World War II, Korea, Vietnam or the Gulf Wars. The committee is charged to forever dedicate the stadium in the memory of, and in honor of, UT students and alumni who gave their lives for their country. Each year, one home football game is designated as Veterans Recognition Day, commemorating the memorial aspect of the stadium and to honor the memory of war soldiers.

1971 - Upper deck added to the west side raising seating capacity to 77,809; artificial turf applied to field. General contractor for this work was a joint venture of two companies: Darragh & Lyda Inc. of San Antonio, Texas and H. A. Lott, Inc. of Houston, Texas.

1977 - Track converted from 440 yards to 400 meters (437.4 yds.).

1986 - The Vernon F. "Doc" Neuhaus–Darrell K Royal Athletic Center completed at the south end of the stadium at a cost of $7 million; the Center was later renamed the W. A. "Tex" Moncrief, Jr.–V. F. "Doc" Neuhaus Athletic Center in 1997 after Royal's name was added to the stadium.

1997 - Fourteen stadium suites added to west side; underside of the stands remodeled, adding a concession plaza and visitors' locker room. In recognition of UT law school alumnus and benefactor Joe Jamail, the University named the football playing field Joe Jamail Field. Stadium capacity reduced by 2,297 seats, bringing capacity to 75,512.

1998 - Upper deck added to the east side including fifty-two new stadium suites and a 13,000-square-foot (1,200 m2) private club room. A total of 3,959 seats were added, bringing capacity to 79,471.

1999 - Track removed; new seats added to the west grandstand and the field was lowered seven feet to accommodate new front-row and field-level seats on the east and west grandstands, bringing capacity to 80,082.

2005 - Bellmont Hall, located in the west side of the stadium, was upgraded to meet newer safety codes set by the Austin Fire Department, the upper deck structure received new water sealing, and the Centennial Room and eighth-floor press box were expanded at a cost of $15 million.

2006 - A 7,370-square-foot (685 m2) high-definitionDaktronicsLED scoreboard, nicknamed "Godzillatron", located in the south end zone, was installed as the centerpiece of $8 million worth of audio/visual improvements. The six large flag poles that previously displayed the Six Flags Over Texas were replaced by smaller flags located atop the new screen. The sound system was also updated and smaller video boards were installed on the east and west sides of the stadium. 432 club seats were added to the west side and approximately 4,000 bleacher seats were added behind the south end zone expanding official seating capacity to 85,123.

2007-2008 - An expansion project costing $149.9 million gave the stadium a new memorial plaza and new multi-level north end zone structure. The new outdoor plaza at the northwest corner is a memorial to veterans, with (the original 1924) bronze tablet honoring Texas World War I deaths, and a monument. The expansion included additional seats with an upper deck, club space, suites, athletic offices, academic-advising areas and a basement with gym space. Demolition of the old north end zone began on December 8, 2006 to move seating closer to the field.[7] The south end zone also became the new seating location of the Longhorn Band beginning in 2008. Overall, the stadium's official seating capacity increased to 94,113.[8]

2009 - A $27 million project[9] brought a new Football Academic Center, a new Hall of Fame, FieldTurf replaced the TifSport Certified Bermuda grass, and replaced the 4,000 south end temporary bleachers with the addition of 4,525 permanent bleacher seats bringing capacity to 100,119.[5]

2011 - Player locker room renovated with 135 new wide-space lockers connected to a state-of-the-art exhaust system, nutrition bar, lounge area with gaming stations, six large LED screens, and a new sound system and speakers.[4]

2013 - FieldTurf installed in 2009 replaced in April 2013 to improve drainage and change the orange in the end zones to more of a "burnt orange".[10]

2015- A $62 million project[6] that will add a practice facility for the women's volleyball team in the basement of the north end zone as well as additional athletic offices. Bellmont Hall will receive facility improvements and become an academic center for kinesiology, health education and fine arts.[6]</>

The scoreboard measures at 81 feet (25 m) tall and 136 feet (41 m) wide with a pixelresolution of 2064 x 848.[11] The scoreboard was installed as part of a US$149.9 million stadium renovation, $8 million of which was spent on audiovisual improvements. The new high definition screen was the centerpiece of these improvements and debuted at the start of the 2006 football season.[12] Previously, two scoreboards were in place, one in the south end, the Freddie Steinmark Memorial Scoreboard and Jumbotron, and one in the north end, a video matrix screen. Both were removed after the 2005 season. The new scoreboard replaced the one in the south end. The north end no longer features a scoreboard as it was removed for the 2008 stadium expansion. The giant Longhorn symbol at the very top was sold on eBay.[13]

A downside for fans is that the screen can be used to allow more obtrusive advertising to be displayed during games.[17] It has been controversial among fans because at some times a large portion (more than 50%) of the screen is being used for advertising and other non-game related graphics.[18][19] This has led to some fans (including Austin American-Statesman commentator Kirk Bohls) calling the new screen "Adzillatron".[20][21] Complaints have also been made about the scoreboard being too loud and about it broadcasting advertisements to those in the stadium, even over the top of the band playing in the stadium.[19][20] In its first usage, the portion of the new screen that was typically used for showing replays and film highlights was approximately the same size as the old video screen.[18][22] More recent games have featured a 16:9 format image centered in a ring of advertisement and score/clock related information. Nevertheless, complaints continue about the advertising, with some fans shouting out "We won't shop/eat/bank there" when advertisements are played loudly in the stadium.[23]

The final planned phase of the stadium's expansion includes the enclosing of the south end zone, completely enclosing the playing field with two levels of seating (not including club seating and luxury boxes). This plan has been part of the University's master plan since at least the early 1990s, as renderings and models of a fully enclosed stadium have existed since that time. If the expanded south end zone seating mirrors the current north end zone seating, which seats approximately 28,500 fans, the expansion could add approximately 24,000 seats to the existing 4,525 south end zone "temporary" bleachers. The stadium's final seating capacity is expected to be between 115,500 and 125,000 when the south end zone is fully enclosed, supplanting The University of Michigan's Michigan Stadium as the largest football stadium in North America and also becoming the second largest stadium in the world. However, the date of the final construction phase to fully enclose the south end zone has not been set nor have any funds been raised. A possible hint at the timeline for construction was released by the University in their plans for the Dell Medical School. Phase 3 of the medical school project includes a campus map showing all of the new buildings in the project highlighted in burnt orange. Among the highlighted areas is a new structure enclosing the south end zone of the stadium.[24] On March 10, 2014, the University announced that they have begun a feasibility study on the completion of the south endzone. "We continue to plan for the future of UT Athletics and work to provide a superior gameday experience for all our fans and stakeholders," said Steve Patterson, Men's Athletics Director. "The south end project is conceptual at this point. Any further planning will depend on a variety of factors to be studied over the next several months." [25]
